This equation describes the electrostatic force acting on a surface.

For info about the math of the equation, see the [http://www.elmerfem.org/blog/documentation/ Elmer models manual], section ''Electrostatic force''.

==Usage==

# After adding an Elmer solver as described [[FEM_SolverElmer#Equations|here]], select it in the [[Tree_view|tree view]].
# Now either use the toolbar button [[Image:FEM_EquationElectricforce.svg|32px]] or the menu {{MenuCommand|Solve → Electricforce equation}}.
# Change the [[#Solver_Settings|equation's solver settings]] or the [[FEM_SolverElmer_SolverSettings|general solver settings]] if necessary.

==Solver Settings==

For the general solver settings, see the [[FEM_SolverElmer_SolverSettings|Elmer solver settings]].

The electricforce equation provides this special setting:
* {{PropertyData|Exec Solver}}: By default the equation is only solved after a timestep passed. This means it is first solved after the solution of other equations converged. When the setting is ''Always'' the equation is solved after every iteration within a time step. (For [[FEM_SolverElmer_SolverSettings#Type|steady-state]] simulations the whole simulation is one time step.)

Description

This equation describes the electrostatic force acting on a surface.

For info about the math of the equation, see the Elmer models manual, section Electrostatic force.

Usage

  1. After adding an Elmer solver as described here, select it in the tree view.
  2. Now either use the toolbar button or the menu Solve → Electricforce equation.
  3. Change the equation's solver settings or the general solver settings if necessary.

Solver Settings

For the general solver settings, see the Elmer solver settings.

The electricforce equation provides this special setting:

  • DataExec Solver: By default the equation is only solved after a timestep passed. This means it is first solved after the solution of other equations converged. When the setting is Always the equation is solved after every iteration within a time step. (For steady-state simulations the whole simulation is one time step.)
